'FORCE AND SUCTION PUMP.

SPECIFICATION forming part 0f Letters Patent N0. 646,668, dated April 3,1900. Application led February '7, 1900. Serial No. 4,322. (No model.)

T0 all whom t may' concern:

Be it known that 1,'EMIL NOPPEL, a citizen of the United States,residing in the .city and county of Philadelphiatate of Pennsylvania,have invented a new an d useful Improvement in Force and Suction Pumps,which improvement is fully set forth in the following speciiication. y

My invention relates to an improvement in pumps; and it consists of asuction-cup which is adapted to be connected with the dischargenozzle ofthe same in a simple, in expensive, iirm, and reliable manner, as willbe hereinafter described.

The figure represents a vertical section of a cup and a side elevationof a portion of a pump embodying my invention.

Referring to the drawing, A designates a portion of a barrel of a pump,and B designates an invertedcup, of elastic or other pliable material,whose lower edge or rim is bifurcated, as at C, and adapted to be heldin contact with a surface to which it is applied by the suction of thesame.

D designates a cap, of metal or other suitable material, which embracesthe upper side of the cup and serves to stiften the same.

E designates the discharge-nozzle of the pump, on which is the iange Fand the end nipple G, the latter having the ilange G- on its terminus.

B designates a socket which is formed by the collars H and J which areintegral portions of the upper wall of the cup at the center thereof,said collars having between them the groove K to receive the wall of anopening centrally in the cap D.

It will be seen that when the nipple G is inserted in the socket B itcompresses the walls of the latter, so that it isl hugged by said socketand firmly held, displacement being further prevented by the flanges Fand G at the opposite ends of said nipple, thus securely connecting thepump with the cup and avoiding the use of nuts, screw-threads, or otherappliances, the integral nature of the socket and cup obvia ting jointsbetween said parts and fastening devices therefor, the advantageouseffects in both cases being evident.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination 'of a pumping` device.`

having a nipple, a cup having a soeketto receive said nipple, and anapertured cap upon the outside of said cup, said cup being provided witha groove that receives the edge por tion of said cap surrounding theaperture therein.

2. The combination of a pumping device having a nipple provided with atapered end, shoulders at the end of said tapered portion, a cup havinga socket to receive said nipple, said socket being retained between saidshoulders, and an apertured cap upon the outside of said cup, said cupbeing provided with a groove to receive the edge portion of the capsurrounding the aperture therein.

3.. The combination of a pump, provided with a nipplea cup having anaperture, eX- tensions or collars integral with said cup and surroundingsaid opening to form a socket for said nipple, the collar or extensionon the outside of said cup being provided with a groove, and anapertured cap upon the outside of said cup, the portion of said capadjacent the aperture therein being situated within said groove.
